Scripps Pier Experiment Benign Conditions High Sea State Conditions

Scripps Pier Experiment: January 6-28, 2008
Objectives:
(1) Ensure all gear is working properly,
(2) Work toward integration of instruments/measurement approaches,
(3) Integrate data with models,
(4) Determine what is missing,
(5) Meet RaDyO science objectives for shallow waters.

Scripps Pier Information:
More information can be found on Ken and Luc's presentation.
(Click on "Meetings" and the checkmark under "Presentations" at the Montreal, Canada RaDyO Planning Meeting.)

  • Latitude: 3252.0'N ; Longitude:11715.4'W.
  • The Scripps Pier juts 320 meters (1,050 feet) into the Pacific Ocean.
  • The Pier deck is ~9 m off the water. Water depth ranges from ~5.5 m - 7 m.
  • Scripps Pier Data can be found at: San Diego Coastal Ocean Observing System and CDIP

    Accommodations:
    Vacation Rentals by Owner (VRBO)
    Marriott Residence Inn, La Jolla
    Hotel La Jolla at the Shores

    Other Notes:
    Luc is working on a network timing source for synchronization purposes (NTPD).
    Ken M. and Luc will figure out the issue with getting keys to the pier.
    Ken M. and Luc will look into rooms for morning daily briefings and longer group meetings.
    They will also look into the 17 x 8' trailer and associated budget.
    Ken M. and Luc will do some more homework on accommodations including group rates for the Marriott and other hotels.
    Be sure to bring all tools and supplies necessary for your equipment and sensors.
